One Jab Flu Shot?

[Guest guest]

May be in the offing--aside from the relevance of one less pathogen for HIV+ individuals to face, I think the fact of this vaccine may point to directions in research for an HIV vaccine. In short, rapidly mutating surface molecules are the WRONG target. At least in flu, it doesn't change that much so we've gotten by with a once a year shot. In HIV, this wouldn't work as it changes so quickly. Of course, we've known that for nearly two decades, but resources are wasted on bullshit studies (maybe to assure we delay discovering an effective vaccine?) /aluminum hat off

It could be stockpiled in advance of a pandemicDr of AcambisNine out of 10 of those who had two doses of the jab ACAM-FLU-A developed antibodies against flu virus.Scientists at Acambis are now working to perfect the formulation before doing larger human trials.Dr of Acambis said: "As a universal vaccine, ACAM-FLU-A can potentially overcome many of the drawbacks of existing influenza vaccines."It can be manufactured at any time of the year, and could be stockpiled in advance of a pandemic or potentially used routinely to ensure population protection against future pandemics."Unique actionCurrent flu vaccines work by giving immunity to two proteins called haemagglutinin and neuraminidase, which are found on the surface of flu viruses.However, these proteins keep mutating which means doctors have to keep making new vaccines to keep up.The Acambis vaccine hones in on a different protein, called M2, which is found on the surface of all A-strains of flu and does not mutate.Professor Ian , a University of Reading virologist, said the jab could end the scramble to produce a new winter jab each year.But he said it would still be some years before it was widely available for patients."Larger trials and tests on a wider range of viruses will be needed before the full potential for pandemic protection can be assured," he said.Story from BBC NEWS:http://news.bbc.co.uk/go/pr/fr/-/2/hi/health/7171118.stmPublished: 2008/01/04 10:18:31 GMT© BBC MMVIII
